Hi,
I am trying to understand the output of hive Explain command. I found the
documentation provided (
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Explain )
to be of little help. Is there any other place where I can find the
detailed documentation on this?
Hiroyuki, were you able to find any detailed docs on this? Or any other
leads?
Thanks
Mohit

Hello,
I have been trying to learn the Hive query compiler and
I am wondering if there is a way to see the result of semantic
analysis (query block tree)
and non-optimized logical query plan.
I know we can get AST and optimized logical query plan with explain,
but I want to know the intermediate results between them.
Also, is there any detailed documentations about Hive query compiler ?
I would be very appreciated if anyone answered my questions.
Thanks,
Hiroyuki
